Garmin Vector 2 Power Meter

Single and dual pedal options. Available from October 2015.

These are Look Keo compatible pedals with six degrees of float. Each pedal pod requires a CR-2032 button cell, and you have the option of just going for power measurement in the left pedal (that's the Vector 2S version). It's easy to move the pedals between bikes (unlike the previous version), but these are obviously only suitable for road use.
